APPARATUS FOR enemas HYnRooAn-BoN OILS.

Application filed Ju1y'8', 1922. serial N6. 575,644.

To all whom it may concern:

Be it known that I, CHAnnns E. Cn r- MAN, citizen of the United States, residing at Fort Edward, inthe county of NVashing ton and State of NewfYork, have invented certain new and useful Improvements in Apparatus for of which the following. is a specification.

This invention relates to an improved apparatus for burning hydrocarbon oils, being similar to the apparatus disclosed in Patent No. 1,386,091, issued to me August 2, 1921, as well as to the apparatus disclosed in Patent No. 1,419,223, issued to me June 13, 1922.

The invention seeks, as one of its princimixture of steam'and oil injected into the retort chamber but wherein a burner will be provided for directing the flame, produced by subsequent combustion of said vapor, of whether the flame is forced or cut down, the flame will play over the retort across the opening'leading into the retort chamber so'that the heated products ofcombustion may always be present atsaid opening to be drawn into said chamber, thus insuring the proper operation of the apparatus.

And the invention has as a still further object to provide an apparatus wherein the discharge horn employed in connection with the retortwill be provided with a jacket through which a supply of heated air will be delivered at the mouth of said horn to become mingled with the vaporous mixture of steam and oil for assisting the combustion thereof and wherein the fiow of air through the jacket around the horn will tend to cool thehorn. or H Other and incidental objects will appear hereinafter.

In the drawings: Figure 1 is a fragmentary longitudinal sec Burning Hydrocarbon Oils,

Figure 2 is a detail sectional view on the Baez-20f Figure 1, and

Figure 3 is a detailsecti onal view on the line 33 ofFigure 1. g

marryi the invention'into effect, I employ a retort'tube'lO closed atone end by a removabletcap or the -,like, to provide a re tort chamber 11 While the opposite end of the tube is bent to form a discharge horn 12, the tube being of uniform diameter throughout its length. In the drawings, I have shown the apparatus in connection with a conventional boileiflldhaving, a-' base 1 1, one, wall of which is, for convenience, indicated at 15, and, as will be observed, the inner end of the retort tubelOis inserted throughsaid wall to extend within the base beneath the bottom" sheet of the boileri Mounted withg ber and leading into thechamberat one side thereofthr'ougih the wall of the jacket 17 is,

as'best shownjin Figure 3 an inletpipe 20 for the heated productsof combustion, this pipe being" disposedlhoriz'ont ally and entering the chamber imrnediatejly at the inner end of the nozzle 19 at substantially right angles thereto. Interposedin the pipe 18 is an appropriate shut-off valve 21. Leading into the steam'jacket'17 at the end thereof adjacent the wall 115 is a steam supply pipe 22 in which is. interposedan appropriate shut-oil valve 23, and leading from the opposite end of said chamber into the oil supply pipe 18 is an outlet pipe 24: for said chamber;

Bolted or otherwise secured at its ends to the wall 15 of the base 14 of the boiler, at the utersi'depf said wall, is a U-shaped jacket 25 surrounding the discharge horn 12; of the. retort" tube; longitudinally into are provided This jacket is split with mating flanges bolted or otherwise secured together so that the sections may be readily assembled about the horn, and formed through the wall 15 at the lower end of said jacket is an opening 26. As will be observed, the discharge horn terminates short of the lower end of the jacket, being provided with suitable lugs 2'? centering the free end of the horn within the jacket, and formed in the jacket near its upper end is a series of spaced air inlet openings 28. Bolted or otherwise secured to the wall 15 at its inner side to surround the opening 26 in said wall is a tube 29 forming, in eiiect, a continuation of the jacket, and detachably mounted upon said tube is a burner 30 lying beneath the retort in a plane therewith. at its upper side, this burner is provided with. jet openings 31, the

burner being otherwise closed with respect to the base of the boiler.

In operation, oil under pressure is fed through the pipe 18 to the nozzle 19 while steam is supplied under pressure through the pipe 22 to the steam jacket 17 and since the burner 30 is located immediately beneath the retort, flame from the burner will play around said jacket for superheating the steam therein. Accordingly, superheated steam will be discharged through the outlet pipe 24: to become mingled with the oil passing through the pipe 18 for atomizing the oil so that a vaporous mixture of oil and steam will be discharged from the nozzle into the retort chamber. The discharge of the nozzle will, of course, create a suction in the pipe 20 so that the heated products of combustion will be coincidently drawn in through said pipe into the retort chamber to become mixed with the vapor therein. I The temperature of said chamber will thus be greatly elevated with the result that the chemical structure of the oil and steam of the vapor will be broken down. From the retort chamber the vapor will then be impelled through the discharge horn 12 to issue from the mouth thereof into the jacket 25, thereby set tingup a suction in the jacket acting to draw in a supply of air through the inlet openings 28 of the jacket so that before the fuel vapor reaches the burner air will be mixed therewith for supplying oxygen auxiliary to that derived from the steam injected through the nozzle 19. As will be seen, the air flowing through the jacket will be caused to traverse the length of the discharge horn so that the air, before becoming mingled with the fuel vapor, will be heated to a high temperature for thus further augmenting the combustibility of the vapor. Practically perfect combustion will accordingly be had at the burner. Furthermore, as will be noted, the air flowing through the jacket 25 discharge horn.

will tend to cool the Attention is now directed to the fact that the burner 30 will direct the flame upwardly around the retort so that regardless of whether the flame is forced by an augmented supply of fuel or is cut down by a restriction of the fuel supply, the flame will, at all times, play over the outer end of the pipe 20 for not only excluding air but also provid ing, at all times, heated products of combustion in the proximity of the outer end of the pipe. Failure in the supply of heated prod nets of combustion at the pipe 20 through deflection or restriction of the flame to, in turn, cause failure of the apparatus, will accordingly be prevented. However, the pipe 20 is located horizontally to open through one side of the retort ratherthan vertically to open through the lower side of the retort so that the flame cannot rise directly into said pipe to cause overheating of the retort chamber.
